MongoDB可使用标准的方法实现日志轮转,即获取到当前日志并开启一个新的。为了实现它,mongod实例通过在文件名称末尾添加UTC(GMT)时间戳的方式重命名当前的日志文件,然后打开这个新的log文件,关闭之前旧的log    文件,并发送所有新的日志信息到新的log文件中。

Rotation Setps

MongoDB标准的日志轮转方法是通过日志轮转命令,或者让mongod进程接受到一个SIGUSER1信号,以下具体的实现方法

1 开启mongod进程,保证appending enabled

mongod -v --logpath /var/log/mongodb/server1.log --logappend

2 在终端查看是否有mongo日志文件

ls /var/log/mongodb/server1.log*

3 如果是Windows系统,打开mongo shell,进入admin数据库并敲入轮转命令,,即

use admin

db.runCommand( { logRotate : 1 } )

如果是Linux系统,则在终端运行 kill -SIGUSR1

4 再次查看结果是否有新的mongo日志文件生成

ls /var/log/mongodb/server1.log*

My auto script and crontab

以下是我用python写的定时脚本,每天产生一个新的log,超过10天的log自行删除

#!/bin/env python
import sys
import os
import commands
import datetime,time

#get mongo pid
mongo_pid = commands.getoutput("/sbin/pidof mongod")
print mongo_pid

#send Sig to mongo
if mongo_pid != '':
    cmd = "/bin/kill -USR1 %s" %(mongo_pid)
    print cmd
    mongo_rotate = commands.getoutput(cmd)
else:
    print "mongod is not running..."

#clean log which > 10 days
str_now = time.strftime("%Y-%m-%d")
dat_now = time.strptime(str_now,"%Y-%m-%d")
array_dat_now = datetime.datetime(dat_now[0],dat_now[1],dat_now[2])
lns = commands.getoutput("/bin/ls --full-time /var/log/mongodb/|awk '{print $6, $9}'")
for ln in lns.split('\n'):
    ws = ln.split()
    if len(ws) != 2:
        continue
    ws1 = time.strptime(ws[0],"%Y-%m-%d")
    ws2 = datetime.datetime(ws1[0],ws1[1],ws1[2])
    if (array_dat_now - ws2).days > 10:
        v_del = commands.getoutput("/bin/rm -rf /var/log/mongodb//%s" % (ws[1]))

在root下crontab -e查看定时任务

0 2 * * * /home/jiangjianjian/mongo_log_rotate.py >/home/jiangjianjian/null 2>&1

How does Go language implement the addition, deletion, modification and query operations of the database? How does Go language implement the addition, deletion, modification and query operations of the database? Mar 27, 2024 pm 09:39 PM

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database.

iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos Jul 18, 2024 am 05:48 AM

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How does Hibernate implement polymorphic mapping? How does Hibernate implement polymorphic mapping? Apr 17, 2024 pm 12:09 PM

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

An in-depth analysis of how HTML reads the database An in-depth analysis of how HTML reads the database Apr 09, 2024 pm 12:36 PM

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
